Discussion
CAD is a genuine improvement on the drawing board in all these respects save one. Which does not apply?
Answer: A
Correct answer: it removes the need to understand projection conventions
CAD draws what it is told, so first and third angle projection, sectioning, hidden detail and the rest remain the draughtsman’s responsibility entirely. What it genuinely gives is revision without redrawing, exact reuse of standard details, and measurement taken directly from the geometry.
